Abstract: 14 FREQUENCY REUSE TECHNIQUE FOR A HIGH DATA RATE SATELLITE COMMUNICATION SYSTEM ABSTRACT Frequency reuse (70) and data coding methods (80, 90) for use in a high data rate satellite communication system (10). The frequency reuse method (70) provides for dual polarization and spatial reuse of transmit and receive beams to provide for a twelve-fold increase in the effective bandwidth and number of users that may be supported by the system (10). Transmit and receive antennas provides multiple, inter- leaved transmit and receive antenna beams. Digital input data at a source user terminal is coded and transmitted from a source user terminal on one of the plurality of receive antennas is demodulated. The received data is demodulated demodulated and is routed so that it may be transmitted to a destination user terminal. The data is then remodulat- ed, multiplexed, and transmitted to the destination user terminal on one of the plurality of transmit beams. The transmitted data is decoded at the destination user terminal to produce the output data. The input and output data processed by the system is digital, and the coding (concatenated coding forward error correction processing) is employed to reduce the sensitivity of communicated data to interference. The presently preferred encoding method comprises Reed-Solomon encoding (42) input data, interleaving (43) the encoded data, and convolutionally encoding (44) the interleaved data and then time division multiplexing (45) and modulating (46) the data. The presently preferreddecoding method comprises demodulating (56) and demu ltiplexing (57) received time division multiplexed data, Viterbi decoding (58) the demultiplexed data, deinterleaving (59) the Viterbi decoded data, and Reed-Solomon decoding (60) the deinterleaved data to produce the output data. Other multiplexing schemes may alternatively be employed. The demodulating and demodulating steps regenerates a high quality digital data stream on the satellite that is communicated to the destination terminal to reduce the effects of uplink interference upon the downlink data stream.

Abstract: An improved aqueous fabric cleaning shampoo composition contains a combination of (a) about 0.5-20% by weight of a fabric cleaning polymer which is a solid at 25 °C and water dispersible or water soluble upon neuturalization with an alkaline compound such as a polymer of methacrylic acid/styrene/n-butyl acrylate, (b) about 0.1-10% by weight of a specific type of wax having a melting point of at least 50 °C such as pressure-emulsified polyethylene wax and (c) about 0.05-5% by weight of a silicone betaine polymer in addition to an effective amount of at least one conventional anionic, amphoteric or zwitterionic surfactant in water at a pH of from about 7 to about 10.5. Such a fabric cleaning shampoo composition not only provides good cleaning and conditioning to fabrics, particularly synthetic fibre fabrics, such as those used in carpets as well as to upholstery and pile fabrics, but also provides soil resistance to the fabric cleaned with such a composition.

Title: Tamper resistant closure cap with bubbled threads
Inventor: NOFER KARL H
IPC: B65D50/04
Filed: 1994-04-14
Granted: 1999-07-13
Abstract: A closure has a central portion with a periphery and a skirt extending from the periphery, a tear strip extending from the skirt, a tamper evident band extending from the tear strip and a movable flange extending from the band.  The flange is hinged so that the tamper evident band has equally spaced windows in it to make it flexible so that it can be stretched over the ring with a very small tolerance or even a negative tolerance relative to the ring.  Once the flange has overridden the ring, a free edge of the flange moves inward to rest against an outer surface of the neck beneath the ring.  The closure can then not be removed from the container without first severing the tabs as the flange will not override the ring during removal of the closure.  The tabs are severed by manually grasping a handle of the tear strip and removing the tear strip. When the tear strip is removed, the closure functions in a conventional manner for opening and closing the container.  The screw thread on the closure is made up of elongated bubbles located end to end.  A core for a mold to make the closure containing the bubbled screw threads can be manufactured using a ring-shaped electrode having a cylindrically-shaped inner surface.  The electrode is connected to a high voltage source and mounted in an electrical discharge machine, there being a contact point on said inner surface for each bubble to be formed in said screw thread.     With previous devices, the closure contains conventional screw threads and dusting is a major problem or, the flange does not contain windows and cannot be manufactured on a large scale with appropriate tolerances.

Abstract: Track sections of industrial conveyor systems are joined in end-to-end relationship using alignment devices that ensure that the internal running surfaces of the rail flanges of the track are free from irregularities at the track joints.          Tubular bushings are located at the ends of the sections on adjacent external surfaces of the rail flanges out of running contact with the moving conveyor components.  When the bushings are brought into register and united to form a connection, proper alignment is achieved and maintained without the need to weld the track sections together at each joint.  This provides a modular track configuration to facilitate the installation and maintenance of conveyor track systems.

Abstract: A system for removably installing a truck equipment onto a truck frame comprises a mechanical support assembly for supporting the equipment on the ground in a tilted position.  A tilt ramp pivotally mounted to the rear free end of the truck frame, is provided with a pair of elongate parallel frame rails. The truck equipment comprises a pair of elongate guide members  to  slide  on  the  frame  rails  and  guide longitudinal movement of the equipment on the ramp. An hydraulic cylinder is mounted between the truck frame and the front end of the ramp to tilt that ramp and thereby enable the guide members to engage the tilted frame rails upon rearward movement of the truck frame toward the truck equipment supported on the ground in the tilted position.  A winch then hauls the truck equipment on the tilted ramp until the equipment reaches a predetermined position in which it is locked by means of hydraulically operated pins.  The truck equipment is then operable.   To remove the truck equipment, the ramp and equipment are tilted and the guide members are unlocked from the frame rails. The rope of the winch is finally uncoiled to slide the tilted truck equipment down the tilted ramp and return that equipment to the tilted position where it can be supported by the mechanical support assembly.   The guide members can then be disengaged from the frame rails of the ramp by moving the truck frame forwardly.

Abstract: In a device for controlling a flow of metal from a casting vessel (2) into a casting mould (3), the inflow of metal is to be controlled by means of a stopper (5), which may be lifted and lowered, according to a preset program and/or by means of a bath-level measuring device (7).  In order to eliminate from such a device any manual intervention at a stopper control lever at the start of casting or in the event of faults etc., a lifting rod (10) together with its vertical guide (12) and its computer-controlled electromechanical drive (13) is to be disposed in a module box (15).  The module box (15) itself is exchangeably fastened to the casting vessel (2) by clamping elements (16).  Furthermore, before casting begins, the stopper drive motor (13) is to be connected by means of electric plug-and-socket connections (37) to the control cabinet (34).  From the start of casting, the stopper movement is controllable exclusively by means of the electric drive (13) and the latter by electric signals.

Abstract: A rotary tool is disclosed, in particular a drill bit, comprising a shaft with cutting edges at the cutting end and with coolant ducts running through the shaft in an essentially longitudinal direction and opening out at the front ends. Two parallel ducts form the loop of a closed coolant circulation system by having sealing units fitted at the outflow ends at the tip of the bit; these sealing units allow a connection to be established between the outflows to create a coolant loop, while being fitted on the inside so as to be fluid-tight. This arrangement allows dry operation of the drill bit.
